Re: NSE - hostrule function passed an empty host object

[Peter Hogg <dev () vokoda com>]

When I run without su privileges, I get some different parts of host,
but still not the traceroute info:


NSE: Script scanning 74.125.230.116.
bin_ip: J}æt
name:
ip: 74.125.230.116

NSE: Script Scanning completed.



Very confused.
